Products classified under HTS 3103.11.00.00
Triple Superphosphate 46% P2O5 Fertilizer
Triple superphosphate (TSP) is a high-phosphorus fertilizer containing 46% P2O5 by weight, produced by reacting phosphate rock with phosphoric acid. It falls under HTS 3103.11.00.00 as a superphosphate with 35% or more diphosphorus pentaoxide, specifically the triple grade variant. Used primarily for root development in crops like corn and soybeans.
Granular Triple Superphosphate 44-47% P2O5
Granulated triple superphosphate provides 44-47% available P2O5 in uniform granules for easy soil application and reduced dust. Classified under HTS 3103.11.00.00 due to exceeding the 35% P2O5 threshold as a superphosphate. Ideal for high-phosphorus demanding crops in bulk agricultural use.
High-Analysis Triple Superphosphate TSP 48% P2O5
Premium high-analysis TSP delivers 48% P2O5 for intensive farming, manufactured without fillers for maximum concentration. It qualifies for HTS 3103.11.00.00 as a superphosphate exceeding 35% P2O5. Commonly used in direct soil application for phosphorus-deficient soils.
Single Superphosphate Enriched to 38% P2O5
Enriched single superphosphate (SSP) boosted to 38% P2O5 through additional phosphoric acid treatment for higher efficacy. Falls under HTS 3103.11.00.00 as it meets the superphosphate definition with ≥35% P2O5. Provides both phosphorus and sulfur for crop nutrition.
Double Superphosphate Granules 40% P2O5
Double superphosphate (DSP) granules offer 40% P2O5 in water-soluble form, produced via wet process phosphoric acid. Classified in HTS 3103.11.00.00 for superphosphates ≥35% P2O5, not retail packaged. Suitable for basal fertilizer applications in row crops.
Premium TSP 46-0-0 Fertilizer Grade
Premium TSP labeled 46-0-0 indicates 46% P2O5, 0% N, 0% K2O, optimized for phosphorus-only nutrition. HTS 3103.11.00.00 applies as high-concentration superphosphate for agricultural bulk use. Enhances flower and fruit development in orchards.
Water-Soluble Triple Superphosphate 45% P2O5
Fully water-soluble TSP at 45% P2O5 for fertigation systems and drip irrigation. Qualifies under HTS 3103.11.00.00 as superphosphate ≥35% P2O5, in bulk form. Prevents phosphorus fixation in alkaline soils.
Industrial Grade TSP 42% P2O5 Bulk
Industrial TSP 42% P2O5 for large-scale farming operations, shipped in bulk railcars. HTS 3103.11.00.00 for superphosphates meeting P2O5 threshold, not retail. Cost-effective phosphorus source for commercial agriculture.
Enhanced Superphosphate 39% P2O5 Granular
Enhanced granular superphosphate reaches 39% P2O5 through proprietary processing for better granule integrity. Classified HTS 3103.11.00.00 as qualifying superphosphate. Reduces application rates while maintaining efficacy.
Crop-Specific TSP for Citrus 47% P2O5
TSP formulated at 47% P2O5 for citrus orchards needing high phosphorus without nitrogen competition. HTS 3103.11.00.00 as pure superphosphate ≥35% P2O5. Supports root and fruit quality in perennial crops.
